REFRIGERATION SYSTEM.

Application filed July 5,

This invention relates to refrigerating apparatus and particularly to converting the refrigerant from thev vapor phase into a liquid phase by means ofan air cooling condenser. The invention contemplates the provision of means for passing large quantities of air in proximity to the radiating elements of the condenser and where a com- I pressor is employed, the air may pass through the cooling jacket of the compressor so that the refrigerating system may be air cooled as distinct from the usual practice in which water is employed as a cooling me dium. w

In the illustrated embodiment of the invention the air impeller is driven by the motor or prime mover and the air for the condenser is passing through a hollow base which forms a conduit for the passage of air preparatory to its flowing through the radieting elements of the condenser and while I prefer the construction illustrated. I do not wish to be limited to the'exact details of construction shown because obviously 95 changes in the arrangement illustrated may be made without departing from the vgeneric embodiment of the invention.

In ,the drawings, a

Fig. 1 is a perspective view of a refrigerating system constructed in accordance with my invention, parts being shown in section, the evaporating coil and motor control beiig eliminated as these are of usual form, an I Fig. 2 is a sectional view through the impelle'r.

Referring now to the drawings by numerals of reference,

l designates a hollow base which may be supported upon a suitable foundation, not shown. The base carries the motor or prime mover 2 illustrated as an electric -motor. Theshaft 3 of the electric motor is connected toj} the shafts of the compressor 5 by a fiexilil-s coupling, best shown in Fig. 2. The flexibldficoupling consists of two collars 6 and 7 fast to the shafts 3 and 4.

The collars 6 and 7 carry flanges 8 and 9 between which is a flexible disk 10 of suitable material, thefianges 8 and 9 and the disk 10 being secured together by bolts 11. The flange 8 extends beyond the perimeter of the coupling and it carries impeller blades 12 engaged in a fan .casing 13 discharging through an opening into the hollow portion 14 of the base 1 and if desired the casing 13 1924.

may discharge into the cooling jacket 15 of the compressor 5 through the medium of a pipe 16, the air exhausting through the cooling jacket through pipe 17.

The hollow base 1 is provided with an air opening 18 over which is fastened a tubular condenser 19, the tubes 20 constituting passageways for the air discharged from the hollow base so that the air may pass through 'the tubes and discharge at the top of the condenser, there being a hood 21 over the top of the condenser, with an outlet opening 22 in line w1th the compressor 5 so that air which exhausts from the condenser may be directed against the compressor to assist in cooling it.

The refrigerant from the evaporator coil may enter the compressor through the pipe 23 in the'usual way and it will be discharged into the condenser through pipe 24. 1 The pipe 25 leads from the condenser to the evaporating coil so the evaporating coil is connected to the pipes 23 and 25 as will be 'well understood; The flexible joint is in eiiect a universal joint to compensate for mis-alignment of the shafts 3 and 4 and j the casing 13 is provided with a centrah opening at each end concentric with the shafts 3 and 4 and since the impeller casing 13 is in line with the prime mover 2 it is obvious that air will be drawn through the prime mover to tend to cool it.

. I am aware that electric motors have been I cooled by causing air to flow through the stators. This feature I do not claim broad- 1y, but I am not aware that prior to my invention an impeller has been utilized in the mamier shown, nor am I aware that prior to my invention an air cooling refrigerating apparatus has been used.

What I claim and desire to secure by Letters-Patent is: 1

Refrigerating apparatus, comprising a chambered base, a motor, an air impeller, a compressor and a condenser mounted on said base, the impeller and the compressor operably connected with the motor, the impeller and thercondenser having connection through the base and the condenser having air discharge toward the compressor, a refrigerant supply'conduit leading to the compressor, a conduit connecting the compressor with the condenser and a refrigerant discharge conduit leading from the condenser. In testimony whereof I afiix my signature. CHARLES W. HACK.
